OptiBoard has an opportunity for a new main sponsor beginning immediately.

Started in 1995, OptiBoard has grown into the largest online site for eyecare professionals in the world. If you have an interest in becoming an OptiBoard sponsor, please let me know. Thanks, Steve

P.S. I have already turned down an online retailer as a sponsor. It would be nice if the eyecare industry would support OptiBoard as much as much as OptiBoard supports them.

Options for an 8.50 Add

Have a gentleman with a +12.00 distance and an 8.50 add. Wearing an aspheric lenticular round seg style. Wants to know what other options are available. My lab guru is away for the day so I thought I'd throw this out here. He'd really prefer a flat seg.

This looks like a Low Vision Rx, where adds are 2X, 3X, etc adn every X= +4.00. So your +8.50 Add is actually a 2X add. www.eyeassociates.com/PDFs/Low%20Vision%20Eyewear.pdf

We just had a Free-form round seg-bifocal with a backside add in +13.50sph +3.50 cyl with a +3.50 add. The front was spherical, but if you stacked the adds you could do the same with one on front, one on back. You could get to +8.00 in theory by using a bifocal blank vs spherical.

It was an ICE-TECH dual zone and came out very thin in 1.74. It looked amazing, like it was only a +7 or so.

Here's the +11.50 with the 8.50 Add. 350 on the front seg and 5 on the back in a 1.67 blended. 4.9 at thickest point on the back bubble.

Nice.

I'm getting dizzy counting all of the optical centers (four)!

Did you start with a 1.67 ST lenticular? I didn't know that was an option. The back was surfaced on a free-form generator, creating the power curve and the round seg? What are the front and back curves, and are they aspheric or optimized in any way? Most importantly, how is your client getting along with them?

Heh! Front curve is an 8 base. I didn't clock the back. I'm uncertain of the rest but as far as he's concerned his vision was noticeably better from the first second he put them on.
